By comparison, jackhammers (sometimes called pneumatic drills or demolition hammers) make quick work of even really hard surfaces like highways, patios and rock walls. That doesn't mean jackhammers are easy to use. They tend to be unwieldy, with some weighing nearly 100 pounds (45 kilograms), meaning that safe operation requires a user with some muscle. In spite of the challenges of using jackhammers, these tools really are necessary for all sorts of major projects. And even though they perform a straightforward and brutal task, modern jackhammers are thoroughly evolved and refined machines with a long history. Keep reading and you'll see just how jackhammers came to be. Machines and power tools of all kinds made labor easier and less physically taxing. But men working in mines and quarries still had to work with pickaxes and shovels, cussing their way through the day. Brawn just wasn't enough for these exhausting jobs. What these laborers really needed was a more powerful way to break through rock to reveal minerals or release stones for construction.
